This invention relates to roof, skylight,

side walls, canopies and area covering constructions andmore p'articularlyjs directed to corrugated structures as for example, constructions using a vitreous sheet, suchas glass having wire netting incorporated therein and formed with a corrugated cross-sectional contour like conventional corrugated iron and asbestos.

One object ofthe invention is to provide a novel construction method of joining corrugated sheets in overlapping relation whereby a. weatherti ht structure is provided. Said en formed of glass sheet being structure w free from breakage due to accident or other causes, and in which construction the erection of coverings of the character described shall be facilitated, saving time and labor as compared with any other construction methods used heretofore.

In the accompanying drawing, in which is 5 shown one of the various possible illustrative embodiments of this invention p i Y Fig.1 is a perspective view of a portion of a roof or skylight construction embodying the invention.

Figs. 2 and 3 are cross-sectional views 1 t eseepeof applicatour 0 like conventional corrugated iron and I I asbestos. 1

' In the improved roof. construction 10, the lass corrugated sheets 11 are mounted in orizontal row A on a suitable supporting structure as shown in Fig. 1, longitudinally extending expansion joi ts E securin said row of sheetsin position.

An asphalt avided as a lining on the under side of the cap 13 facing the sheets. Where the supporting structure is of steel fabrication, the sheetsll are supported on suitable purlins '12, comand the caps 13 are secured to said purlins for anchoring the sheets in position by any suitablefmeans'such as bolts 15 and clip 16.

The edge portions lliof the sheets 11 are bearing.

The knife-edge ledges ofthe m e 0 scribed, a pair of corrugated sheets, posicontacting with the glass sheets 11 readily permits unrestricted expansion or contraction of the joint structure. Dust has been found to settle in the passages P which automatically builds a practical and efiicient seal between said members and the glass sheets. The members 20 may have one end 20 tapered and terminated with an angle extension 22 which serves as a stop for abutting the end edge of the sheet 11 and as a guide for condensation to drain moisture to the corrutioned with their ends in overlapping relation having a space therebetween, and a filler comprising a'plurality of identical members interposed between the lapped portions to form a joint, said members having their adjacefnt edges spaced from each other and forming drainage channels in the troughs of said corrugated sheets. e

Ina construction ofthe character deto have a thiclmess corresponding to the conlapped sheet portions, and spaced upstanding ledges on said filler contacting said sheets extending lengthwise the joint and transversely the sheet corrugations, said members having means to provide drain channels extending through the joint.

4. As an article of manufacture a filler member adapted to be interposed between spaced overlapping portions of a pair of corrugated sheets to form a joint comprising a non-absorbent packing, preshaped to correspond to the cross-sectional curved contour of the space between said sheet portions and extending from a point'spaced from the center of one trough of a corrugation over the crest portion thereof to a point spaced from the center of the next adjacent trough whereby a drainage channel will be formed between the adjacent filler members when so interposed.

In testimony whereof I aflix my signature. 7
